WINDOW SEAT.

Application filed February 20, 1922, Serial No. 538,072. Renewed May 27, 1924.

To all whom it may concern Be it known that I, GEORGE M. BU- CHANAN, a citizen of the United States, residing at North Braddock, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in WVindow Seats, of which the following is a specification.

This invention relates to supporting de vices, and more particularly to a window seat specially adapted for use when cleaning windows from the outside and for other purposes.

One of the main objects of the invention is to provide a window seat of simple construction and operation which may be readily adjusted to suit the particular construction of the window in connection with which it is to be used. A further object is to provide a window seat possessing great strength in which the hinge connections of the braces are relieved of all strain. Another object is to provide a seat of the character stated of simple construction and neat appearance which may be produced at small cost. Further objects will appear from the detailed description.

In the drawings Figure 1 is a side view of the window seat as applied;

Figure 2 is an underneath view of the seat folded;

Figure 3 is a section taken substantially on line 33 of Figure 1.

The device includes a seat board 1 to which are fastened securing bars 2 each provided at its outer end with a hook element 2 adapted for engagement over the sill of a window as indicated in Fig. 1. Each bar 2 is provided with a plurality of openings 3 adapted for reception of securing bolts 1 passing through board 1, wing nuts 5 being threaded on the lower ends of these bolts. By means of the bolts 4 and openings 3 the effective length of bars 2 can be readily ad justed to suit circumstances.

Brace bars 6 connected by cross strips 7 are loosely secured at their outer ends, by pins 8, in U-brackets 9 secured to the underface of board 1. Outward movement of bars 6 about pins 8 is positively limited by folding braces 10 secured at their inner ends to brackets 11 secured to the underface of board 1. The outer ends of brace bars 6 are cut to provide abutment faces 12 which are adapted to contact with the inner face of a relatively thick brace strip 13 secured to the underface of board 1 adjacent to the outer end thereof. To permit brace bars 6 to move into contact with strips 13, each of the bars is provided with a slot 14 through which pin 8 passes. When the device is in operative position the lower ends of bars 6 rest against the side of the structure and the upper ends of these bars rest against strip 13 so that this strip and the bars support the seat board 1 and the weight of the person upon the same thus relieving the hinge connection of the brace bars of all strains. This provides a window seat of simple construction and great strength capable of supporting very heavy weight.

What I claim is I 1. In a device of the character described, a seat board, means for securing the inner end of the seat board to a window sill, a brace strip secured across the underface of the seat board adjacent to the outer end thereof, brackets fixedly secured to the underface of the seat board inside of the strip, brace bars fitting through said brackets and provided with longitudinally extending slots, pins secured through the brackets and passing through said slots, and means for limiting movement of the brace bars away from the seat board, the outer ends of the brace bars being adapted for contact with said brace strip when the bars are in operative osition.

2. n a device of the character described, a seat board, means for. securing the inner end of the seat board to a window sill, a brace strip secured across the under face of the seat board adjacent to the outer end thereof, U-shaped brackets secured to the underface of the seat board inside of the strip, brace bars fitting snugly through said braclc. ets and provided with longitudinally eX- tending slots, pins secured through the brackets and passing through said slots, and

means for limiting movement of the brace bars away from the seat board, the outer ends of the brace bars being adapted for contact with the inner edge of said brace strip when the bars are in operative position.

In testimony whereof I affix my signature.

GEO. M. BUCHANAN.
